Friends star Matthew Perry said he suffered from opening night jitters when he stepped on stage in London, where he is starring in David Mamet's play Sexual Perversity in Chicago.

He said: "I was about as scared as I can get without vomiting or having a heart attack."

Perry and his Friends co-stars will be leaving the long-running hit TV show when the series ends after next season.

He said the cast had not wanted to talk about it.

"Jennifer Aniston would start to cry whenever it was approached at all," said the 33-year-old actor.

"What I would like to say about the show ending - it is so scary and so emotional because we have been doing it for 10 years - is that a chapter is going to close in my life and it's my job to find the next one."
